TypeName

IdentityAccessors.Default.TypeName handles complete assembly qualified type names.

// Get identity accessor
IIdentityAccessor<Type> identityAccessor = IdentityAccessors.Default.TypeName;
// Construct identity
IIdentity identity = identityAccessor.Create(typeof(string));

IdentityAccessors.Default.TypeNameWithoutAssembly handles type names without assembly parts.

// Get identity accessor
IIdentityAccessor<Type> identityAccessor = IdentityAccessors.Default.TypeNameWithoutAssembly;

Construction

TypeName.Create() constructs IIdentity from an instance of the native type.

// Construct identity
IIdentity identity = IdentityAccessors.Default.TypeName.Create(typeof(string));

"String" → "System" → "6.0.0.0" → "System.Private.CoreLib" → 7cec85d7bea7798e → "neutral"

TypeNameWithoutAssembly.Create() constructs without libarary parts.

// Construct identity
IIdentity identity = IdentityAccessors.Default.TypeNameWithoutAssembly.Create(typeof(string));

"String" → "System"

Deconstruct deconstructs IIdentity back into native type.

// Create id
IIdentity id = IdentityBase.CreateNamespace("System").AddName("String").SetReadOnly();
// Deconstruct identity parts into native value
Type type = IdentityAccessors.Default.TypeName.Deconstruct(id);

Print and Parse

C# System.Type has three kinds of type names.

.Name is a simple name part without namespace.

// Get type
Type type = typeof(System.String);
// "String"
string name = type.Name;

.FullName is namespace+name without the assembly. This is context-dependent identity, library being the context.

// "System.String"
string fullname = type.FullName;

.AssemblyQualifiedName is a complete name with libary, version and culture. This identity can be used context-free.

// "System.String, System.Private.CoreLib, Version=6.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"
string assemblyqualifiedName = type.AssemblyQualifiedName!;

IdentityAccessors.Default.TypeNameWithoutAssembly and IdentityAccessors.Default.TypeName parses from all of the string formats System.Type produces.

//
string typename = "System.String, System.Private.CoreLib, Version=6.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e";
// Parse assembly qualified type name
IIdentity id1 = IdentityAccessors.Default.TypeName.MemoryAccessors.Parse(typename);
// Parse full name type name
IIdentity id2 = IdentityAccessors.Default.TypeNameWithoutAssembly.MemoryAccessors.Parse(typename);
// "Name("String") → Namespace("System") → Version("6.0.0.0") → Library("System.Private.CoreLib") → PublicKeyToken(7cec85d7bea7798e) → Culture("neutral")"
Console.WriteLine(id1);
// "Name("String") → Namespace("System")"
Console.WriteLine(id2);

TypeName prints C# type system compatible strings.

// Construct identity
IIdentity identity = IdentityAccessors.Default.TypeName.Create(typeof(string));
// "System.String, System.Private.CoreLib, Version=6.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"
string assemblyQualified = IdentityAccessors.Default.TypeName.MemoryAccessors.Print(identity);
// "System.String"
string fullname = IdentityAccessors.Default.TypeNameWithoutAssembly.MemoryAccessors.Print(identity);

Arrays

Arrays are represented as "Array" part where and with Int32 label for array rank.

Type type = typeof(string[]);
IIdentity id = IdentityAccessors.Default.TypeNameWithoutAssembly.Create(type);

Array[1] → Name("String") → Namespace("System")

Generic Parameters

Generic type parameters are constructed as IIdentity.Components.

//
Type type = typeof(Dictionary<string, int>);
// 
IIdentity id = IdentityAccessors.Default.TypeNameWithoutAssembly.Create(type);

Name("Dictionary`2") → Namespace("Generic") → Namespace("Collections") → Namespace("System")
├── [0] Name("String") → Namespace("System")
└── [1] Name("Int32") → Namespace("System")

Inner Type

Inner types have multiple 'Name' parts. Generic type parameters are on the tailing 'Name' part.

// Create type
Type type = typeof(OuterPart<object>.InnerPart<int>);
// Create identity
IIdentity id = IdentityAccessors.Default.TypeNameWithoutAssembly.Create(type);
// Print
Console.WriteLine(id.PrintTree());

public class OuterPart<T>
{
    public class InnerPart<Y> { }
}

Name("InnerPart`1") → Name("OuterPart`1")
├── [0] Name("Object") → Namespace("System")
└── [1] Name("Int32") → Namespace("System")

Other

Extension method .PrintTree() extends Type classes. This is used for verbose debug printing.

string print = typeof(IList<int>).PrintTree(assemblyQualified: false);

Name("IList`1") → Namespace("Generic") → Namespace("Collections") → Namespace("System")
└── [0] Name("Int32") → Namespace("System")
